WINDMILL-REGULATOR.

Specification of Letters Patent.

Application filed March 11, 1914. Serial No. 824,009.

others skilled in the art to which it appertains to make and use the same.

This invention relates to windmills and has special reference to a regulator for windmills arranged to operate in conjunction with a water tank so as to throw the mill in or out of service according to the depth of water in the tank.

The principal object of the invention is to provide an improved regulator of this description which will be subject to minimum of wear on the wearing parts and which will be simple in construction and readily repaired when necessity arises.

Another object of the invention is to provide a windmill regulator which will be so arranged by means of an improved construction as to insure complete working of the pawls convenient in such devices.

With the above and other objects in view the invention consists in general of certain novel details of construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and Figure l is a side elevation of a regulator constructed in accordance with this invention. Fig. 2 is a view of the regulator taken at right angles to Fig. 1. Fig. 3 is a section on the line 33 of Fig. 1. Fig. 4 is a section on the line 44 of Fig. 1. Fig. 5 is a section on the line 5-5 of Fig. 1. Fig. 6 is a section on the line 66 of Fig. 1.

In carrying out the objects of this invention there is attached to' the windmill frame 10 a pair of side plates 11 which have laterally disposed feet 12 provided with bolt receiving openings 13. Through these openings 13 extend the bolts 14 which are used to connect the side plates to the frame. These side plates are'held in spaced relation by means of a back plate or bar 15 which is riveted between the side plates so that there is formed a trough shaped structure wherein is slidably mounted a ratchet bar 16 which is held in position in the trough by suitable guards 17, these guards constitute the U- shaped plates with the bights in the Us arcuate in cross section so as to permit sliding of the bar without the teeth catching. This ratchet bar is connected by means of a wire 18 to the vane controlling device (not shown) which is arranged as usual so that by pulling down on the wire the vane will be shifted parallel the wheel and the wheel consequently brought up edgewise to the 1 wind so that the latter will have'no effect upon it. However, when the wire is released the vane will operate and swing the wheel into the wind.

Secured to the side plates 11 is a pair of plates 19 which extend over the ratchet bar 16 and pivoted between the outer ends of these plates is a curved pawl 20 which is adapted to engage the teeth of the bar 16.

At 21 is the usual reciprocating pump rod i and secured on opposite sides of this rod are brackets 22 which engage/the ends of the operating levers 23, these latter being pivoted as at 24 to the plates 11, these levers 23 extending over thebar 16 and pivoted between their outer ends is a pawl 25 similar in all respects to the pawl 20.

Secured to a suitable place on the frame is a bracket 26 wherein are mounted the pulleys 27.

At 28 is a float and on this float is supported a pulley 29. The pawl 20 has attached thereto one end of a cable 30 which is preferably of flexible wire and this cable runs over one of the pulleys 27 beneath the pulley 29, back over the other pulley 27, and has its remaining end attached to the pawl 25. The pawls 20 and 25 are so arranged as to tend to constantly engage the bar 16 when the float 28 is raised by the water in the tank, the latter not being deemed necessary to be shown. However, to assist in supporting the weight of the cable between the float and the pulley 27 there is employed a spring 31 which has one end connected to an eye 32 and carries on its other end a small pulley around which istrained a flexible wire 34 which has its ends connected to the cable 30 between the pulley 27 and the respective pawls. By means of this pulley and spring arrangement, the tension on all parts of the cable 30 will be kept uniform and when the water in the tank falls the weight of the float 28 pulls uniformly on both ends of the cable 30 thus releasing the pawls from the bar 16. This leaves the bar free to rise and the vane is turned outward throwing the wheel to the wind and pumping begins. As the water in the tank rises, the float rises and the pawls move to engage the bar 16, the spring 81 assisting the weight of the pawls in overhauling the cable 80. WVhen the pawls are engaged the reciprocation of the rod 21 causes the pawl 25 to move up and down and during this operation the bar 16 is moved downward by the engagement of the pawl therewith, being held from again rising by the pawl 20. This operation continues until the bar 16 has moved down to such an extent as to cause the wire 18 to throw the vane parallel with the wheel and thus bring said wheel edgewise to the wind whereupon the rod 21 ceases to reciprocate.

There has thus been provided a simple and eflicient device of the kind described and-of the character specified.

It will be obvious that many minor changes may be made in the form and construction of this invention without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described, but it is wished to include all such as come properly within the scope claimed.

Having thus described the invention, what is claimed as new, is

1. In a windmill regulator, a support, a vertically reciprocable ratchet bar carried by said support, a locking pawl pivoted to said support and engaging saidbar, apump rod, an oscillating lever pivoted to said support and connected to said pump rod, an operating pawl carried by said oscillating lever and normally engaging said bar, a tank float, a flexible cable having its end connected to respective pawls and having a running connection with said tank float, and guide pulleys over which said cable is trained.

2. In a windmill regulator, a support, a

,vertically reciprocable ratchet bar carried by said support, a locking pawl pivoted to said support and engaging said bar, a pump rod, an oscillating lever pivoted to said support and connected to said pump rod, an operating pawl carried by said oscillating lever and normally engaging said bar, a tank float, a flexible cable having its end connected to respective pawls and having a running connection with said tank float, guide pulleys over which said cable is trained, a spring having one end connected to said support, a pulley carried by the other end of said spring, and a flexible strand having its ends connected to said cable between the guide pulleys and the ends thereof, said strand extending around the pulley on the spring.

In testimony whereof, I afiix my signature, in the presence of tWo witnesses.
